Links with no accessible text (empty <a></a>, image-only no alt, icon-only no aria-label) are unidentifiable to screen readers.
Source: WCAG 2.1 SC 2.4.4
Image-only links need alt text on the image (or aria-label on the link) so screen readers can announce them.

Images without alt text are invisible to screen readers.
Each image without alt text is a WCAG 1.1.1 failure — invisible to screen-reader users, lost from Google Image Search.
Learn more ▾ ▴
WCAG 2.1 Level A requires text alternatives for non-decorative images. Empty alt='' is fine for decorative; meaningful images need descriptive text. Common fixes: CMS audit + bulk add, build-time linter (alt-text-required ESLint rule), CI gate on Lighthouse a11y score.

An image inside a link with no alt creates an empty link.
Image-only links with no alt create empty links — screen-reader users hear 'link' with no destination context.

An <a><img></a> with no img alt is the worst-case for accessibility: AT announces the link but can't describe where it goes. Either add alt to the image OR add aria-label to the link.

Accessibility
These checks highlight opportunities to improve the accessibility of your web app. Automatic detection can only detect a subset of issues and does not guarantee the accessibility of your web app, so manual testing is also encouraged.
ARIA
Focusable descendents within an `[aria-hidden="true"]` element prevent those interactive elements from being available to users of assistive technologies like screen readers. Learn how `aria-hidden` affects focusable elements.

Names and labels
Informative elements should aim for short, descriptive alternate text. Decorative elements can be ignored with an empty alt attribute. Learn more about the `alt` attribute.

Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.
Without a skip-nav link, keyboard users tab through every nav item before reaching content — every page, every visit.
Learn more ▾ ▴
WCAG 2.4.1 (Bypass Blocks) requires a mechanism to skip past repeated content. The standard implementation is a 'Skip to main content' link that's the first focusable element, visually hidden until focused. Three lines of HTML + four of CSS.

Placeholder-only labels disappear when the user starts typing — they must remember what the field was for.

Placeholders are NOT labels. They vanish on input, fail color contrast checks (most are gray), and don't satisfy WCAG SC 3.3.2. Always use a real <label> alongside (or aria-labelledby).
